Vyatta is a Linux based distro that ease the set up of VPN, Routers, antivirus.... It has a really small footprint on your system as it only requires something like 800M to be installed and is based on Debian. On the top of that, it offers configuration wrappers to facilitate service settings.

This tutorial will explain how to set up 2 Border Gateway Protocol (BGP) boxes to route the traffic from one Autonomous System (AS) to the other using Vyatta. Vyatta Community Edition 4.1.4 was used during this set up.

3. Setting BGP

As told earlier on, vyatta-bgp1 will advertise AS 1 with network 1.1.1.0/24 to its neighbor vyatta-bgp2 handling AS 2 andvyatta-bgp2 will advertise AS 2 with network 2.2.2.0/24 to its neighbor vyatta-bgp1 handling AS 1

They will use a common password for this communication, which is BGPtutorial.
